Developing Year 2000 Compliant Software
Operational Range for Data: 1930 through 2029 using two-digit shortcuts or user configurable
How the product runtime handles dates:
While all versions of Visual Basic will handle years greater than 1999 (in a 4-digit format), passing a 2-digit year in a date (such as 7/3/45) requires Visual Basic to interpret to what century the date corresponds.
Two-digit shortcut handling:
Visual Basic 5.0 converts 2-digit years to 4-digit years based on the default in the Automation libraries for all date functions. Visual Basic 5.0 shipped with version 2.20.4054 that converts 2-digit years to the 2000s if the 2-digit year is between 00 and 29. If the 2-digit year is between 30 and 99, the date is converted to the 1900s. The product will function into the 21st century through the end of year 2030 in accordance with industry standard 100-year date windowing. Developers can modify this date window to their own needs as described in the Windows 98 control panel or as described in the white paper, "Developing Y2K Compliant Applications with Visual Basic"
Recommended practices to develop year 2000 compliant applications with this Development Tool:
Users can use their own set of rules instead of relying on the defaults native to Visual Basic. For example, users may enter only a 2-digit year and have 00 to 49 correspond to the years 2000 to 2049 and have 50 to 99 correspond to the years 1950 to 1999.
When accepting a date string from the user, test the format of the string to determine the number of digits entered for the year. According to the rules for this sample application, 1/11/45 is in the year 2045, and not in the year 1945. Within the code for the application, change the string to use the appropriate 4-digit year, and then convert that date string with the 4-digit year into a date variable.

Note for Enterprise Edition Users
Visual SourceSafe contains a small cosmetic display issue when using the history pre-dialog:
1. In the History pre-dialog where users can specify a date range to do a history on ("show me the History between 1/1/97 and 2/24/2000), if users specify a date after the year 2000, it will be treated as a date in the 1900s. The same problem exists on the command line.
2. The history pre-dialog in version 5.0 does not accept 4-digit years.
The issues described above are cosmetic display problems. Data is stored correctly and clock rollover to the year 2000 will not cause data loss.
The most restrictive structure Visual SourceSafe uses for dates is a long integer containing the number of seconds since January 1, 1970.
